In the air compressor industry, from time to time, I hear many friends say that the oil and gas separation core is burning and igniting, and the ultimate cause has not been found. Because we didn't see it in person, we can only analyze it theoretically.

The analysis of the reasons for the combustion or explosion of the oil-gas separation core is as follows:

1. The oil-gas separation core itself will not burn and ignite, and there must be a condition that the kind of fire and combustion-supporting gas can burn and ignite. 

2. The static electricity generated by the oil-air separation core is not easy to generate fire, because the compressed air passes through the glass fiber to generate static electricity, and the static electricity can only work when it is dispersed to the compressor shell. Its role is to absorb very little. When the irregularly moving fine oil particles on the fiber, the more they absorb, the larger the oil particles are generated. The weight of the oil is heavier than the air, and it drops to the lower part of the oil-air separation core and returns to the lubrication system. This is a Brownian motion. If the static electricity does not dissipate, the principle of Brownian motion cannot be achieved, so the reason why a conductive sheet should be added to the gasket of the oil-gas separation core. Therefore, static electricity is not the cause of burning.

3. One of the conditions for the combustion of the oil-gas separation core is that the combustion-supporting gas is compressed air. Another kind of fire, there are several reasons for the fire:

(1). It is the kind of fire produced by the collision of objects. Objects refer to rusty iron, carbon deposits, weld inspections, or metal particles worn out by metal parts. . .

(2). It is the oil used by the compressor. Compressor oil is very important. Whether the flash point of the oil meets the requirements and whether its anti-oxidation ability meets the standard. The oil is constantly changing under pressure, at 80°C and 100°C. The amount of oil vaporization is different under the condition of degree of degree, and the amount of vaporization of oil at 100 degree is 10 times that of 80 degree. Therefore, the greater the amount of compressor oil vaporized, the more carbon deposits will be produced. When the soot is continuously affected by the temperature of the compressor, it will continue to heat until a fire is produced.

(3) Whether the pressure holding valve of the compressor is damaged, if it is damaged, if several compressors are in use at the same time, it is easy to produce gas collision, and the most likely to produce fire.

The above is the reason why the oil and gas separation core in the air compressor is on fire based on theoretical knowledge. I hope that when you encounter this situation, you can check it in detail to avoid more serious production losses.
